研究 Research

丸山研究室では,構造物や機械の健全性評価技術の開発・発展を目的として,(超)音波を用いた非破壊評価・モニタリング技術について研究を行っています. 主に,固体中での(超)音波の伝搬や散乱現象の解明や適切な利用のため,数値シミュレーションを活用したアプローチを行っています.
Our research objectives are to develop and advance evaluation techniques for the integrity of structures and machinery. To achieve this, we use numerical simulation methods to elucidate and appropriately utilize ultrasonic wave propagation and scattering in solids.
